force a connection and test that it worked from a pre-existing sql.DB note the required driverNameĭb = sqlx.NewDb(sql.Open("sqlite3", ":memory:"), "sqlite3") You can create an sqlx.DB via Open or by creating a new sqlx DB handle from an existing sql.DB via NewDb: It maintains a connection pool internally, and will attempt to connect when a connection is first needed. This is why creating a DB does not return an error and will not panic. Connecting to Your Database ¶Ī DB instance is not a connection, but an abstraction representing a Database. Because the underlying implementation was inaccessible, sqlx.Row is a partial re-implementation of sql.Row that retains the standard interface.
#Actix rt github code
Handle types all embed their database/sql equivalents, meaning that when you call sqlx.DB.Query, you are calling the same code as sql.DB.Query.
#Actix rt github driver
Since it's infrastructureless, I recommend mattn's sqlite3 driver to start out with:
#Actix rt github install
You will want to install sqlx and a database driver. If you need help getting started with Go itself, I recommend these resources:īecause the database/sql interface is a subset of sqlx, all of the advice in these documents about database/sql usage also apply to usage of sqlx. There are other resources of excellent information about using SQL in Go: You should make sure to check all errors in an actual program. It will not cover setting up a Go development environment, basic Go information about syntax or semantics, or SQL itself.įinally, the standard err variable will be used to indicate that errors are being returned, but for brevity they will be ignored. We’ll look at both a simple GET request as well as a mutating POST request.Sqlx is a package for Go which provides a set of extensions on top of the excellent built-in database/sql package.Įxamining Go idioms is the focus of this document, so there is no presumption being made that any SQL herein is actually a recommended way to use a database. Having just looked at the external API, the handlers are actually rather simple.
#Actix rt github free
Anyone can create a free account and create API credentials, but the concepts of this post can be applied to any other web API as well.
In this example, I’ll be using the Timeular Public API as a proxy target, because I’m very familiar with it. The web application we’ll look at in this post exposes a small REST API, which proxies the incoming requests to another API. Keep in mind that I’m both new to Rust and very new to Actix, so while what I threw together here works and does what I want it to do, it might not be the best/most optimal way of doing things. In general, Rust is definitely not at the stage Java, node.js, Ruby or Go are when it comes to the Web ecosystem, but there is steady progress, which is documented here. For this example, I decided to use Actix, because it seems mature and well documented/maintained. There are several ways to go about this in Rust - there are several frameworks with different strengths. In this case, we’ll take a look at a basic web application in Rust.
This is often either a small CLI tool or a web application. One thing I like to do when learning a new language is to do something I’m conceptually familiar with, to see how it looks in the new language. There is definitely a rather steep learning curve compared to learning other languages, but when it clicks and something compiles, it tends to work well in my experience so far, which is very rewarding. I’ve been playing around with Rust quite a bit for the last several months and I have been loving it. This post and example were based on Actix 0.7 A Basic Web Application with Rust and Actix-web
